Jose Luis Mendilibar has been sacked by Real Valladolid.
Sunday night's draw against relegation rivals Almeria left Valladolid just one point above the drop zone and the club have won only three times in their past 31 league games.
Club president Carlos Suarez announced the decision as they unveiled latest signing Asier del Horno and also revealed that reserve team coach Onesimo would take over first-team duties.
A statement on the club website read: "Jose Luis Mendilibar is not Real Valladolid coach any more. President Carlos Suarez announced the sad decision on Monday morning, a day after the draw against Almeria.
"Onesimo, until now the reserve coach, will be his replacement. The new coach will take his first training session on Tuesday, after which he will be presented to the media.
"The decision is sad for the club because Mendilibar is a professional who is much loved at the Zorrilla, as much for his human side as for his outstanding work since he took charge of the team.
"But the club decided to look for drastic solutions to combat a negative run of results which is continuing to stretch.
"Jose Luis Mendilibar is going, but his time at Valladolid leaves a profound stamp on the club. The name Mendilibar has been etched in capital letters in the club's history."
